Document Summary

Challenges in presenting information in a clear way evident when trying to explain it to 4-year-old. Chapter approaches human development from hereditary perspective, seeking to determine how one"s genotype (genes one inherits) expressed as phenotype ( observable or measurable characteristics). Review evidence for hereditary contributions to psychological attributes ex intelligence, personality, mental health, and patterns of behaviour. Implies: many noteworthy phenotypic characteristics influenced by genes passed to us by our parents. Must start conception: moment when an ovum released by woman"s ovary and on way to uterus via fallopian tube fertilized by a man"s sperm. Establish what is inherited at conception, can examine mechanisms by which genes influence characteristics we display. Sperm cell penetrates lining of ovum, biochemical reaction repels other sperm, preventing them from repeating fertilization process. Sperm cell begins to disintegrate, releasing genetic material; ovum releases its genetic material, and new cell nucleus forms around hereditary information.
